1 / 14 page  4-Character 5 x 7 Dot Matrix Alphanumeric Programmable Display TM with Built-in CMOS Control Functions Lead (Pb) Free Product - RoHS Compliant 2006-01-23 1 PD243X, PD353X, PD443X PD243X PD353X PD443X DESCRIPTION These Programmable Displays are four digit display sys- tem modules. The characters are 5.08 mm by 3.56 mm (0.20" by 0.14") (PD243X), 6.86 mm by 5.08 mm (0.27" by 0.20") (PD353X), and 11.43 mm by 6.86 mm (0.45" by 0.27") (PD443X) 5 x 7 dot matrix arrays constructed with the latest solid state technology in light emitting diodes. Driving and controlling the LED arrays is a silicon gate CMOS inte- grated circuit. This integrated circuit provides all neces- sary LED drivers and complete multiplexing control logic. Additionally, the IC has the necessary ROM to decode 128 ASCII alphanumeric characters and enough RAM to store the display’s complete four digit ASCII message with special attributes. These attributes, all software pro- grammable at the user’s discretion, include a lamp test, brightness control, displaying cursors, alternating cursors and characters, and flashing cursors or characters. The CMOS IC also incorporates special interface control circuitry to allow the user to control the module as a fully supported microprocessor peripheral. The module, under internal or external clock control, has asynchronous read, write, and memory clear over an eight bit parallel, TTL compatible, bi-directional data bus. Each module is fully encapsulated within a package 25.4 x 17.8 x 5.08 mm (1.0" x 0.7" x 0.2") (PD253X), 35.6 x 18.3 x 7.24 mm (1.4" x 0.72" x 0.285") (PD353X), and 38.1 x 20.8 x 7.24 mm (1.5" x 0.82" x 0.285") (PD443X). The standard 20 pin DIP construction with two rows spaced at 15.2 mm (0.6") on 2.54 mm (0.1") centers is wave solderable. See the end of this data sheet or refer to Appnotes 18, 19, 22, and 23 for further details on handling and assembling OSRAM Programmable Displays.
